Indsætte anden baggrund i css

Hej.

jeg sidder og er ved at ligge nogle billeder ind på en cms hjemmeside som er lavet med Jalbum.

Jalbum laver sit eget css script og cms køre med et andet.

billederne er lagt ind i cms som object men vil meget gerne have baggrunden jeg bruger i cms til at ligge over i Jalbums css fil

men kan ikke finde ud af hvor i Jalbums cms fil jeg skal referer til det billed jeg bruger i cms

billedet er i 1 x 200 og skal så strækkes så det bliver en hel baggrund eller ligges side om side som cms selv gør

filen i Jalbum ser ud som følger:
